"I'm very disappointed. We should today be talking about the
finals series... I'm terribly disappointed to be even talking about
this today," Greenberg said.

"We had a very detailed discussion with all 16 clubs (about
end-of-season celebrations), the eight clubs that weren't playing,
so the expectations were very, very clear, and the Bulldogs have
let down the game today.

"I've got no problems with people celebrating the end of their
season, as long as they do it respectably.

"On this occasion, they've made some poor decisions and poor
choices, and that ultimately gives the game a black eye and that's
what I'm disappointed about today."

Greenberg said the players have left themselves and the club
open to ridicule, and that their behaviour is a blight on the
game.

However, the NRL boss remained coy on what punishment will be
handed down.

"It's embarrassing for the players as individuals themselves,
it's embarrassing for their club, and it's embarrassing for the
game," Greenberg said.

"I'm not going to speculate on what sanctions or actions we will
take, I'll wait until I get the full details of the report because
I don't have all the details at the moment."

Canterbury apologised for their players' behaviour, and issued a
statement on Tuesday morning saying their actions were
"unacceptable and a bad look for the game".

"In regard to images from the team's get together on Monday, the
club accepts that they were unacceptable and a poor reflection on
the individuals involved and the club," the club said.

"The players are aware of their responsibilities and the
standards required when representing the club and yesterday's
behaviour was unacceptable and a bad look for the game."

Rugby League Players' Association CEO Ian Prendergast
acknowledged the poor behaviour of the Bulldogs players, but was
critical of the "intrusive" nature of the reporting.

"We share the disappointment of other stakeholders regarding the
impact that these incidents can have on the perception of the game
and players, particularly given all of the impressive things that
players are doing, on and off field, and the positive direction
that the game is heading in," Prendergast said.

"We're also concerned about the intrusive nature of the
reporting involved here... while we accept players have stepped out
of line on this occasion, they are entitled to let their hair down
at the end of a tough year."
